By bidding on this item, you help an ELK kid to participate in Environmental Learning for Kid's year-round science education program.  ELK serves low-income, culturally diverse youth from the Denver metro area, and participating in ELK gives them science education, outdoor learning, and college opportunities that they many never otherwise have. Plus, you get an ELK hoodie, an ELK short sleeve polo, and an ELK T shirt. You let us know the sizes you need (adult and kid sizes)!
